Further, most new homes are insulated from heat loss using modern materials. As well as preventing heat from escaping, these can also prevent moisture from escaping. Consequently, this leads to a buildup of moisture which precedes issues with condensation and mould. The Nuaire Drimaster PIV Unit has easy to use hall controls. Everything you need to control your unit is located in the ceiling diffuser for easy access. It’s important to note that this unit doesn’t in itself provide any extraction of water. Instead, this PIV unit works by pumping fresh air into your home. When this happens, the old air is forced out and your condensation levels are lowered. All Nuaire Drimaster PIVS units are designed to perform with extremely low noise levels, always ensuring the best level of whole house air ventilation is maintained. PIV works by drawing fresh air in through the unit that’s usually, but not always, installed in your loft. This air is then filtered and gently diffused at ceiling level, creating a positive pressure within the home that forces air pollutants out through the natural leakage gaps found in every UK property, both old and new. When would you recommend using a PIV unit?

Choosing between a PIV unit and a dehumidifier depends on your specific needs and the environment you are trying to improve. Your Drimaster-Eco PIV system is designed to be mounted in the loft space where it draws fresh air through the G4 grade filters, and inputs it at ceiling level into the home. Positive Pressurisation is the most effective method of retrofit whole-home ventilation and is a tried and trusted cure for condensation dampness. This model’s non-disruptive installation makes it ideal for repairs and maintenance schemes making it a favourite with social house providers. So you have a loft space and you have heard about PIV units? Well, if you want to make use of your loft and keep your home fresh and dry then a PIV unit is a must-have. PIV stands for Positive Input Ventilation, it was invented in the 70’s by Nuaire. This revolutionary device provides a steady supply of fresh air to the house via the loft. This fresh air cascades through the house replacing the old, stale and damp air. Consequently, excess condensation and damp are eradicated along with mould.The installation of a PIV unit can greatly increase indoor air quality and prevent many of these issues. PIV does also rely on the availability of some loft space to put the unit in, so is not ideally suited to apartments or homes with vaulted ceilings or flat roofs. However, there are wall-mounted alternatives available too.

No, unless you’re running on a high speed, you’ll barely hear it. How will the air in my home escape? PIV systems create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout a property and is our most popular method of whole house ventilation. Energy recovery ventilation systems provide a controlled way of ventilating a home while minimising energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh (but cold) outside supply air.There are numerous sensors you can use as a bonus. Choose between the carbon dioxide detector or the remote humidity sensor. There is also a four-button switch you can keep anywhere in the home to have control over the boost function. This switch also gives you the ability to control the heater in case you desire manual adjustment. The general rule of thumb is that anytime you notice a reduction of quality air in your home, start by replacing the filter. Nuaire Drimaster Installation On the other hand, a dehumidifier is specifically designed to reduce humidity levels in the air by extracting moisture from the air. They can be particularly useful in damp environments, where there is a high risk of mold and mildew growth. Nuaire Drimaster PIV is a whole-house form of air ventilation which is designed to supply fresh air to the whole property. In some cases, where there is a remote wet room (kitchen, ensuite, bathroom, WC or utility room) we also advise fitting extractor fans. If you are experiencing issues with high humidity levels and dampness, then a dehumidifier would be the better option. However, if your main concern is improving indoor air quality and preventing condensation, then a PIV unit may be a better choice. PIV Unit FAQs Do you require a professional to install your PIV unit?

The principle behind the functionality of the PIV unit is the use of a small fan. This fan has various speed settings that can be altered according to the size of your home or the severity of any damp issues. Fan speed is selected on the PIV unit controller, air is then blown into the house from the loft. Most lofts are insulated in “breathable” materials which allows the PIV unit to draw fresh air from outside. There is no need to vent the unit externally as the natural breathability of your loft is all that is required. Please note some lofts are insulated by non-breathable materials, this would render the use of a PIV unit sub-optimal. It is also known that fumes from detergents, gas outlets, paints and odours can pollute the air around your home. Given that a normal person breathes up to 11000 litres of air per day, good air quality is imperative. Poor indoor air quality can cause diseases such as asthma and other breathing system difficulties. Another alternative upgrade on the HC model with the ability to link to a choice of wireless controls and interactive sensors: including the relative humidity (RH) and carbon dioxide sensors which automatically increase the fans speed when the target setting on the sensors are met. Nuaire Drimaster PIV is a whole house air ventilation system that works by drawing in fresh, filtered air into a property from outside. These can be either installed in a loft space or on a wall in a flat or apartment. They ensure that a continuous supply of air is supplied into the home to eliminate or significantly reduce condensation.The Nuaire Drimaster PIV Unit is easy to install and the guide even comes complete with the instructions for DIYers or professional installers to follow. It teaches everything from the installation in the loft to how to set up those sensors.
